Secure Messaging Apps

Privacy Matters is an independent comparison resource focused on the security and privacy of messaging apps. Its detailed ratings help readers assess how well popular services protect messages, attachments, personal information, and metadata. The comparison covers apps including Google Messages, Apple iMessage, Facebook Messenger, Element, Signal, Telegram, Threema, Viber, WhatsApp, Wire, Session, SimpleX, and X.

Rather than offering messaging software itself, Privacy Matters organizes information about each app’s privacy practices and security features. Its assessments examine encryption defaults, cryptographic methods, open-source availability, independent audits, reproducible builds, anonymous sign-up, contact verification, data collection, and possible disclosure to authorities. The site also compares company and infrastructure jurisdictions, funding, transparency reporting, and privacy policies, while explaining concerns and suggested improvements for individual apps.

A ratings table, app filters, and supporting details make the information easier to explore. Privacy Matters also provides a change log, an About and FAQ section, contact information, and a GitHub link. The resource is intended to help users make more informed choices about secure private messaging.
